Analysis of Transient Thermal Choking Processes in a Model Scramjet Engine

O'Byrne, Sean; Doolan, Matthew; Olsen, S; Houwing, A Frank

Description

Shadowgraph flow visualization and floor static pressure measurements have been used to examine the transient behavior of a thermally choked combusting flow. Experiments were performed to examine the effect of varying inlet Mach number and fuel-air equivalence ratio on the nature and extent of the interaction. In all cases a sudden increase in static pressure was measured, followed by a highly turbulent region of sonic flow that was seen to propagate upstream along the duct. The nature of the...[Show more]
